Question

The majority of the nutrients in
the ocean comes from which
source?

A. from tsunamis

B. from nutrients that wash into the ocean from the continents

C. from the atmosphere

Answer 1

Answer: B

Explanation:

The nutrients that wash off of the continents (waste products, sediment) are often rich in essential minerals to plankton and other microscopic aquatic life, which in turn are the base of the marine food chain.

Tsunamis are too infrequent and do not dredge up any sediment most of the time, and C is not correct because nutrients don't just rain from the sky.
